Change in coreboot[master]: util/kconfig: Uprev to Linux 5.3's kconfig
by Patrick Georgi (Code Review) 13 Jul '21

Patrick Georgi has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/37152 ) Change subject: util/kconfig: Uprev to Linux 5.3's kconfig ...................................................................... util/kconfig: Uprev to Linux 5.3's kconfig This was originally several commits that had to be squashed into one because the intermediate states weren't able to build coreboot: - one to remove everything that wasn't our own code, leaving only regex.[ch], toada.c, description.md and Makefile.inc - one to copy in Linux 5.3's scripts/kconfig and adapt Makefile.inc to make the original Makefile work again. TODO: - more commits that bring back our modifications, both directly in the code and as a diff in a patches/ subdirectory.
